Regarding the casement window equipped.

片開き窓、たてすべり出し窓や片開きドア等の障子（扉ともいうが、以下、障子と総称する。）においては、障子を開いた状態からハンドルを持って回転させて閉める際に、ハンドルを持つ手が開口枠に挟まれることを防止するため、障子が開いた状態では、ハンドルが回動しないようロックするハンドルの誤動作防止装置が提案されている（例えば、特許文献１参照。）。 For sliding doors such as single-opening windows, vertical sliding windows and single-opening doors (also referred to as doors, hereinafter collectively referred to as sliding doors), when the sliding door is opened and held by the handle, the handle In order to prevent the holding hand from being caught in the opening frame, there has been proposed a handle malfunction preventing device that locks the handle so that the handle does not rotate when the shoji is open (see, for example, Patent Document 1).

この特許文献１の障子（扉）におけるハンドル機構では、障子の先端の縦框にハンドルのハンドル軸が貫通してハンドル軸の回動を往復動に変換する、例えばラックとピニオン機構等から連動装置を設けている。そして、この連動装置と一体で縦框に設けられた開閉機枠の溝内にスライド体を配置し、このスライド体の下端には障子先端の縦框の側面に沿って上下に形成された溝内に連動棒または連動桿等と呼ばれる連動部材を連結すると共に、連動部材の先端に施解錠装置（ロック機構部）を連結し、施解錠装置により障子を開口枠に施錠したり、解錠している。 In the handle mechanism for the shoji (door) of Patent Document 1, the handle shaft of the handle penetrates through the vertical frame at the tip of the shoji to convert the rotation of the handle shaft into reciprocating motion, for example, from a rack and a pinion mechanism or the like. Is provided. Then, the slide body is arranged in the groove of the switch frame provided integrally with the interlocking device in the vertical frame, and the lower end of the slide body has a groove formed vertically along the side surface of the vertical frame at the tip of the shoji. An interlocking member called interlocking rod or interlocking rod is connected inside, and a locking/unlocking device (lock mechanism part) is connected to the tip of the interlocking member, and the shoji is locked or unlocked in the opening frame by the locking/unlocking device. ing.

そして、この特許文献１の障子におけるハンドル機構では、ハンドルのハンドル軸が貫通ししてハンドル軸の回動を往復動に変換する連動装置とは別体の連動部材に長孔部とその長孔部と連続した大径孔部とからなる切欠部を設ける一方、その切欠部に大径部及び小径部を有する係合部から構成されたトリガーを設けてハンドルの誤動作防止装置を構成している。 Further, in the handle mechanism of the shoji disclosed in Patent Document 1, the long hole portion and the long hole are formed in the interlocking member that is separate from the interlocking device that penetrates the handle shaft of the handle and converts the rotation of the handle shaft into reciprocating motion. While providing a notch formed of a large diameter part and a continuous large-diameter hole, a trigger formed of an engaging part having a large-diameter part and a small-diameter part is provided in the notch to form a handle malfunction preventing device. ..

この特許文献１のハンドルの誤動作防止装置では、障子が閉まった状態では、連動部材が上下に移動可能であり、トリガーの大径部が連動部材の切欠部の大径孔部に係合しないため、施解錠装置は作用せず、ハンドルを回転させて、障子を開けることができる。 In the handle malfunction prevention device of Patent Document 1, the interlocking member can move up and down when the shoji is closed, and the large diameter portion of the trigger does not engage with the large diameter hole portion of the cutout portion of the interlocking member. The locking/unlocking device does not work, and the shoji can be opened by rotating the handle.

その一方、障子が開いた状態では、上下動する連動部材に設けられている大径孔部がトリガーの大径部と係合して連動部材の上下動を阻止し、この阻止によってハンドルの回転をロックして、障子を閉めた際、開口枠に指が挟まれることを防止する。 On the other hand, when the shoji is open, the large-diameter hole provided in the vertically moving interlocking member engages with the large-diameter part of the trigger to prevent the interlocking member from moving up and down, and this obstruction causes the handle to rotate. The lock prevents the fingers from being caught in the opening frame when the shoji is closed.

次に、以上のように構成された実施の形態１のハンドルの誤動作防止装置１の動作について説明する。 Next, the operation of the malfunction prevention device 1 for a handle of the first embodiment configured as described above will be described.

＜障子３が開口枠２に閉められた状態＞
まずは、障子３が開口枠２に閉められた状態から説明する。 <The state that the shoji 3 is closed by the opening frame 2>
First, a state in which the shoji screen 3 is closed by the opening frame 2 will be described.

障子３が開口枠２に閉められた場合、図２や、図２におけるＡ−Ａ線断面を示す図９、さらには図２の主要部分を拡大して示す図１０に示すように、開口枠２に取付けられた被当接部材２１における被当接部２１ｃ１に第１進退部材１１ｂの先端当接部１１ｂ４が当接しているので、第１進退部材１１ｂは図９上、Ｘ１方向に押されて退行した状態で、圧縮バネ１１ａも収縮した状態にある。 When the shoji screen 3 is closed by the opening frame 2, as shown in FIG. 2, FIG. 9 showing a cross section taken along the line AA in FIG. 2, and FIG. 10 showing an enlarged main part of FIG. Since the tip end contact portion 11b4 of the first advancing/retreating member 11b is in contact with the abutted portion 21c1 of the abutted member 21 attached to No. 2, the first advancing/retreating member 11b is pushed in the X1 direction in FIG. In the retracted state, the compression spring 11a is also in a contracted state.

その際、第２進退部材１１ｃは、図１０に示すように、第１進退部材１１ｂの第２進退部材遊嵌部１１ｂ２に収容され、その方向変換斜溝１１ｃ２に第１進退部材１１ｂの方向変換ピン１１ｂ３が嵌っており、図１０において下方向であるＹ１方向へ最も退行（退避）した最大退避状態にある。 At that time, as shown in FIG. 10, the second advancing/retreating member 11c is accommodated in the second advancing/retreating member loosely fitting portion 11b2 of the first advancing/retreating member 11b, and the direction changing oblique groove 11c2 thereof changes the direction of the first advancing/retreating member 11b. The pin 11b3 is fitted, and is in the maximum retracted state in which it is most retracted (retracted) in the Y1 direction, which is the downward direction in FIG.

この場合、図２や図９、図１０等に示すように、ハンドル１２のハンドル軸１２ａに装着されたカム部材１２ｂがハンドル１２の回動に従って回動しても、第２進退部材１１ｃはＹ１方向へ最も退行した最大退避状態にあるので、カム部材１２ｂの先端部が第２進退部材１１ｃの先端係合部１１ｃ３に係合しない。 In this case, even if the cam member 12b mounted on the handle shaft 12a of the handle 12 rotates in accordance with the rotation of the handle 12, as shown in FIGS. Since it is in the maximum retracted state in which the cam member 12b is most retracted in the direction, the tip portion of the cam member 12b does not engage with the tip engaging portion 11c3 of the second advancing/retreating member 11c.

そのため、障子３が開口枠２に閉められた状態では、ハンドル１２を図２等に示すような水平状態から図１１に示すような垂直状態に回動させても、カム部材１２ｂの先端部が第２進退部材１１ｃの先端係合部１１ｃ３に係合しないので、自由に回動させることができる。 Therefore, when the shoji 3 is closed by the opening frame 2, even if the handle 12 is rotated from the horizontal state as shown in FIG. 2 to the vertical state as shown in FIG. Since it does not engage with the tip engaging portion 11c3 of the second advancing/retreating member 11c, it can be freely rotated.

その結果、ハンドル１２の回動に応じて施解錠装置（図示せず。）を機能させて、障子３を開口枠２に施錠（ロック）したり、あるいは開口枠２に対し解錠（フリー）状態にすることができる。 As a result, the locking/unlocking device (not shown) is caused to function in accordance with the rotation of the handle 12 to lock (lock) the shoji 3 in the opening frame 2 or unlock (free) the opening frame 2. Can be in a state.

尚、この説明では、例えば、図２や図１０に示すようにハンドル１２が水平（横向き）状態にある場合は、施解錠装置（図示せず。）が解錠して、障子３を開口枠２に対しフリー（開閉自在）状態にする一方、図１１に示すようにハンドル１２が鉛直（下向き）状態にある場合は、施解錠装置（図示せず。）が施錠して、障子３が開口枠２にロックされ開かない状態にあるものとするが、この反対でも良い。 In addition, in this description, for example, when the handle 12 is in a horizontal (horizontal) state as shown in FIGS. 2 and 10, the locking/unlocking device (not shown) unlocks the shoji 3 to be an opening frame. 2, while the handle 12 is in the vertical (downward) state as shown in FIG. 11, the locking/unlocking device (not shown) locks and the shoji 3 opens. It is assumed that the frame 2 is locked and cannot be opened, but the opposite is also possible.

＜障子３を開口枠２から開けた状態＞
次に、障子３が開口枠２から開けられた状態を説明する。 <The state that the shoji screen 3 is opened from the opening frame 2>
Next, a state in which the shoji screen 3 is opened from the opening frame 2 will be described.

上述したように、図２や図１０に示すようにハンドル１２が水平（横向き）状態にある場合、施解錠装置（図示せず。）は解錠状態にあり、障子３は開口枠２に対しフリー（開閉自在）状態にあるので、ユーザがハンドル１２を掴んで開放方向へ押すと、障子３は開口枠２に対し図１２や図１３におけるＺ１方向に徐々に開いていく。 As described above, when the handle 12 is in the horizontal (sideways) state as shown in FIG. 2 and FIG. 10, the locking/unlocking device (not shown) is in the unlocked state, and the shoji 3 is positioned relative to the opening frame 2. Since it is in a free (openable/closable) state, when the user holds the handle 12 and pushes it in the opening direction, the shoji 3 gradually opens in the Z1 direction with respect to the opening frame 2 in FIGS. 12 and 13.

すると、開口枠２側の被当接部２１ｃ１に当接していた第１進退部材１１ｂは、図１２や図１３に示すように、その先端当接部１１ｂ４が開口枠２側の被当接部材２１から離れ、圧縮バネ１１ａの弾性力によってＸ２方向に進行する。 Then, as shown in FIGS. 12 and 13, the first advancing/retreating member 11b that was in contact with the contacted portion 21c1 on the side of the opening frame 2 has its tip end contacting portion 11b4 on the contacted member on the side of the opening frame 2. 21 and moves in the X2 direction by the elastic force of the compression spring 11a.

第１進退部材１１ｂがＸ２方向に進行すると、図１４および図１５に示すように、第１進退部材１１ｂの方向変換ピン１１ｂ３もＸ２方向に進むので、Ｙ方向ガイドピン１１ｃ１，１１ｃ１と装置ケース１０のＹ方向ガイド孔１０ｅとによってＹ方向にスライド可能な第２進退部材１１ｃは、その方向変換斜溝１１ｃ２に嵌って案内される第１進退部材１１ｂの方向変換ピン１１ｂ３のＸ２方向への移動によってＹ２方向、すなわち図１４および図１５においてハンドル軸１２ａの方へ進行する。 When the first advancing/retreating member 11b advances in the X2 direction, as shown in FIGS. 14 and 15, the direction changing pin 11b3 of the first advancing/retreating member 11b also advances in the X2 direction. Therefore, the Y direction guide pins 11c1 and 11c1 and the device case 10 are connected. The second advancing/retreating member 11c slidable in the Y direction by the Y direction guide hole 10e of the first advancing/retreating member 11b is guided by being fitted in the direction changing oblique groove 11c2 by the movement of the direction changing pin 11b3 in the X2 direction. It advances in the Y2 direction, that is, toward the handle shaft 12a in FIGS. 14 and 15.

ここで、障子３を開口枠２から開ける場合、上述したように施解錠装置（図示せず。）を解錠状態にするためハンドル１２は水平（横向き）状態にあるので、ハンドル１２のハンドル軸１２ａに取付けられたカム部材１２ｂは、図１４および図１５に示すように鉛直方向の下向き、すなわちＹ１方向を向いている。 Here, when the shoji screen 3 is opened from the opening frame 2, the handle 12 is in a horizontal (sideways) state in order to unlock the locking/unlocking device (not shown) as described above. The cam member 12b attached to 12a is directed downward in the vertical direction, that is, in the Y1 direction, as shown in FIGS. 14 and 15.

そのため、第２進退部材１１ｃがＹ２方向に移動すると、第２進退部材１１ｃの先端係合部１１ｃ３が、カム部材１２ｂのカム部１２ｂ１の先端部に係合する。 Therefore, when the second advancing/retreating member 11c moves in the Y2 direction, the tip end engaging portion 11c3 of the second advancing/retreating member 11c engages the tip end portion of the cam portion 12b1 of the cam member 12b.

すると、障子３を開口枠２から開けた状態では、図１４や図１５に示すように、ハンドル１２は水平（横向き）状態にあり、第２進退部材１１ｃの先端係合部１１ｃ３がカム部材１２ｂの先端部に係合し、カム部材１２ｂを介しハンドル軸１２ａの回動を間接的に禁止するので、ハンドル１２は水平（横向き）状態から回動できないことになる。 Then, when the shoji screen 3 is opened from the opening frame 2, the handle 12 is in a horizontal (horizontal direction) state as shown in FIGS. 14 and 15, and the tip engaging portion 11c3 of the second advancing/retreating member 11c is in the cam member 12b. Since the rotation of the handle shaft 12a is indirectly prohibited via the cam member 12b by engaging with the distal end of the handle 12, the handle 12 cannot rotate from the horizontal (sideways) state.

その結果、ユーザは障子３を開口枠２から開けた状態では、ハンドル１２が水平（横向き）状態から回動しないので、障子３を閉める際にハンドル１２を掴んでいる指等を開口枠２に挟むことを防止できる。 As a result, the user does not rotate the handle 12 from the horizontal (sideways) state when the shoji screen 3 is opened from the opening frame 2, and therefore the finger or the like holding the handle 12 when closing the shoji screen 3 is placed on the opening frame 2. It can be prevented from being pinched.

従って、実施の形態１のハンドルの誤動作防止装置１によれば、ハンドル軸１２ａが貫通する装置ケース１０内に、障子３が開口枠２に閉められた場合、ハンドル軸１２ａの回動を許可する一方、障子３が開口枠２から開けられた場合、ハンドル軸１２ａの回動を禁止するハンドル軸回動制御部１１を設けたため、障子３の縦框３１の幅やデザインに影響を与えることなく、しかもその縦框３１に設けるべき他の金具を制限することがない共に、障子の製作範囲最小高さの制約を緩和するハンドルの誤動作防止装置を提供することができる。 Therefore, according to the handle malfunction preventing device 1 of the first embodiment, when the shoji 3 is closed by the opening frame 2 in the device case 10 through which the handle shaft 12a penetrates, the handle shaft 12a is allowed to rotate. On the other hand, when the shoji screen 3 is opened from the opening frame 2, the handle shaft turning control unit 11 for prohibiting the turning of the handle shaft 12a is provided, so that the width and the design of the vertical frame 31 of the shoji screen 3 are not affected. In addition, it is possible to provide a handle malfunction preventing device that does not limit other metal fittings to be provided on the vertical frame 31 and alleviates restrictions on the minimum height of the shoji manufacturing range.

また、装置ケース１０内にハンドル軸回動制御部１１を設けてハンドルの誤動作防止装置１を構成したため、ハンドルの誤動作防止装置１に加工誤差があったり、経年変化が発生した場合には、ハンドル１２と共に装置ケース１０を取外してその中のハンドル軸回動制御部１１を修理したり、装置ケース１０毎交換することで対応可能となるので、加工誤差や経年変化にも容易に対応することができる。 Further, since the handle malfunction control device 1 is configured by providing the handle shaft rotation control section 11 in the device case 10, when the handle malfunction control device 1 has a processing error or a secular change, the handle malfunction control device 1 can be operated. Since it is possible to deal with the problem by removing the device case 10 together with the device case 12 and repairing the handle shaft rotation control portion 11 therein, or replacing the device case 10 with each other, it is possible to easily cope with a processing error and a secular change. it can.

尚、上記の説明では、ハンドル１２のハンドル軸１２ａは、断面が正方形のハンドル軸１２ａで説明したが、本発明では、これに限定される必要はなく、断面が長方形や多角形等でも勿論良い。 In the above description, the handle shaft 12a of the handle 12 has been described as a handle shaft 12a having a square cross section, but the present invention is not limited to this, and the cross section may be rectangular or polygonal. ..

また、上記の説明では、第１進退部材１１ｂには方向変換ピン１１ｂ３を設ける一方、第２進退部材１１ｃには方向変換斜行溝１１ｃ２を設けて説明したが、本発明では、これに限らず、第１進退部材１１ｂに方向変換斜行溝１１ｃ２を設ける一方、第２進退部材１１ｃに方向変換ピン１１ｂ３を設けるようにしても勿論良い。 Further, in the above description, the first advancing/retreating member 11b is provided with the direction changing pin 11b3, while the second advancing/retreating member 11c is provided with the direction changing oblique groove 11c2, but the present invention is not limited to this. Of course, the first advancing/retreating member 11b may be provided with the direction changing oblique groove 11c2, while the second advancing/retreating member 11c may be provided with the direction changing pin 11b3.

また、上記の説明では、障子３先端の縦框３１に往復動変換装置（図示せず。）の往復動を施解錠装置（図示せず。）に伝達する往復動する連動部材３１ａを設けて説明したが、本発明ではこれに限らず、ハンドル軸１２ａで直接、施解錠装置（図示せず。）を駆動する場合は、往復動変換装置（図示せず。）や連動部材３１ａは省略することができる。 In the above description, the reciprocating interlocking member 31a for transmitting the reciprocating motion of the reciprocating motion converting device (not shown) to the locking/unlocking device (not shown) is provided on the vertical frame 31 at the tip of the shoji screen 3. Although described, the present invention is not limited to this, and when the locking/unlocking device (not shown) is directly driven by the handle shaft 12a, the reciprocating motion converting device (not shown) and the interlocking member 31a are omitted. be able to.

実施の形態２
上記の実施の形態１の説明では、ハンドル軸回動制御部１１を、弾性部材である圧縮バネ１１ａや、Ｘ方向に進退動する第１進退部材１１ｂ、およびＸ方向とは直交するＹ方向に進退動する第２進退部材１１ｃから構成して説明したが、本発明ではこの構造に限定するものでは無く、実施の形態２のように構成しても良い。 Embodiment 2
In the above description of the first embodiment, the handle shaft rotation control section 11 is configured such that the compression spring 11a that is an elastic member, the first advancing/retreating member 11b that moves back and forth in the X direction, and the Y direction that is orthogonal to the X direction. The second advancing/retreating member 11c is configured to move forward and backward, but the present invention is not limited to this structure, and may be configured as in the second embodiment.

つまり、実施の形態２のハンドルの誤動作防止装置１は、例えば、図１６（ａ），（ｂ）に示すように、ハンドル軸回動制御部１１を、装置ケース１０の揺動中心軸１０ｇを中心に揺動する揺動フック１１ｄと、ねじりバネ（トーションバネ）１１ｅとにより構成したことを特徴とする。 That is, in the malfunction prevention device 1 for a handle according to the second embodiment, for example, as shown in FIGS. 16(a) and 16(b), the handle shaft rotation control unit 11 is connected to the swing center shaft 10g of the device case 10. It is characterized in that it is constituted by a swinging hook 11d swinging in the center and a torsion spring (torsion spring) 11e.

揺動フック１１ｄは、装置ケース１０の揺動中心軸１０ｇを中心に揺動するもので、先端側には開口枠２側の被当接部材２１の被当接部２１ｃ１に当接する先端当接部１１ｄ１を有する一方、後端側にはハンドル１２のハンドル軸１２ａに直接、係合する後端係合部１１ｄ２を有している。 The swing hook 11d swings around the swing center shaft 10g of the device case 10, and has a tip end abutting end portion that abuts the abutted portion 21c1 of the abutted member 21 on the opening frame 2 side. While having the portion 11d1, the rear end side has a rear end engaging portion 11d2 that directly engages with the handle shaft 12a of the handle 12.

ねじりバネ（トーションバネ）１１ｅは、その中心が装置ケース１０の揺動中心軸１０ｇに挿入されており、一端部は揺動フック１１ｄの先端当接部１１ｄ１に係止されている一方、他端部は装置ケース１０のバネ係止部１０ｈに係止され、揺動フック１１ｄの先端当接部１１ｄ１を常時、開口枠２側の被当接部材２１の方向に付勢する。 The center of the torsion spring (torsion spring) 11e is inserted into the swing center shaft 10g of the device case 10, and one end of the torsion spring 11e is locked to the tip abutting portion 11d1 of the swing hook 11d, while the other end. The portion is locked by the spring locking portion 10h of the device case 10, and always urges the tip end contact portion 11d1 of the swing hook 11d toward the contacted member 21 on the opening frame 2 side.

つまり、図１６（ａ）に示すように、障子３が開口枠２に閉められた状態では、開口枠２に取付けられた被当接部材２１の被当接部２１ｃ１に、揺動フック１１ｄの先端当接部１１ｄ１が押圧されており、揺動フック１１ｄの後端係合部１１ｄ２がハンドル１２のハンドル軸１２ａに係合しない。 That is, as shown in FIG. 16A, when the shoji screen 3 is closed by the opening frame 2, the swinging hook 11d is attached to the contacted portion 21c1 of the contacted member 21 attached to the opening frame 2. Since the front end contact portion 11d1 is pressed, the rear end engagement portion 11d2 of the swing hook 11d does not engage with the handle shaft 12a of the handle 12.

そのため、この場合には、ハンドル１２は自由に回動することが可能で、ハンドル１２の回動に応じて施解錠装置（図示せず。）により、障子３を開口枠２に施錠したり、あるいはフリー（開閉自在）状態にすることができる。 Therefore, in this case, the handle 12 can freely rotate, and the door 3 is locked in the opening frame 2 by a locking/unlocking device (not shown) according to the rotation of the handle 12. Alternatively, it can be in a free (openable and closable) state.

これに対し、障子３が開口枠２から開けられると、揺動フック１１ｄの先端当接部１１ｄ１は開口枠２側の被当接部材２１に当接せず押圧されなくなるので、図１６（ｂ）に示すように、ねじりバネ１１ｅによって半時計回りに回動する。 On the other hand, when the shoji 3 is opened from the opening frame 2, the tip end contact portion 11d1 of the swing hook 11d does not contact the contacted member 21 on the opening frame 2 side and is not pressed, so that FIG. ), it is rotated counterclockwise by the torsion spring 11e.

その結果、図１６（ｂ）に示すように、揺動フック１１ｄの先端当接部１１ｄ１とは反対側の後端係合部１１ｄ２がハンドル１２のハンドル軸１２ａに直接、係合して、ハンドル軸１２ａの回動を禁止するので、ハンドル１２の回動を防止できる。 As a result, as shown in FIG. 16B, the rear end engaging portion 11d2 of the swinging hook 11d opposite to the front end abutting portion 11d1 directly engages with the handle shaft 12a of the handle 12, and the handlebar 12a. Since the rotation of the shaft 12a is prohibited, the rotation of the handle 12 can be prevented.

従って、実施の形態２のハンドルの誤動作防止装置１によれば、障子３先端の縦框３１に設けられ、ハンドル軸１２ａが貫通する装置ケース１０内に揺動フック１１ｄおよびねじりバネ１１ｅからなるハンドル軸回動制御部１１を設けたため、実施の形態１のハンドルの誤動作防止装置１と同様に、障子３の縦框３１の幅やデザインに影響を与えることなく、しかもその縦框３１に設けるべき他の金具を制限することがない共に、障子の製作範囲最小高さの制約を緩和するハンドルの誤動作防止装置を提供することができる。 Therefore, according to the handle malfunction preventing device 1 of the second embodiment, the handle including the swing hook 11d and the torsion spring 11e is provided in the device frame 10 which is provided on the vertical frame 31 at the tip of the shoji 3 and through which the handle shaft 12a penetrates. Since the shaft rotation control unit 11 is provided, like the malfunction prevention device 1 for a handle according to the first embodiment, it should be provided on the vertical frame 31 without affecting the width and design of the vertical frame 31 of the shoji screen 3. It is possible to provide a malfunction preventing device for a handle which does not limit other metal fittings and relaxes the constraint on the minimum height of the shoji making range.

尚、上記実施の形態１，２の説明では、ハンドルの誤動作防止装置１の装置ケース１０を障子３先端の縦框３１内に内蔵させて説明したが、装置ケース１０はハンドル軸１２ａを貫通していれば十分であるので、障子３先端の縦框３１内ではなく、縦框３１の外側に突出するように設けても勿論良い。 In the above description of the first and second embodiments, the device case 10 of the handle malfunction preventing device 1 is incorporated in the vertical frame 31 at the tip of the shoji 3, but the device case 10 penetrates the handle shaft 12a. Since it is sufficient if it is provided, it may of course be provided so as to project outside the vertical frame 31 instead of inside the vertical frame 31 at the tip of the shoji screen 3.

また、被当接部材２１は別体の部品ではなく、先端当接部１１d１が当接する形状を開口枠２と一体に設けておいても良い。 Further, the abutted member 21 may not be a separate component, but may be formed integrally with the opening frame 2 so that the tip abutting portion 11d1 abuts.
